Abstract

THIS INVENTION IS WITHIN THE SCOPE OF LIQUID FILTRATION AND DEPURATION FACILITIES, ESPECIALLY WATER, OF THE TYPE THAT INCLUDES A WATER CIRCULATION LOOP TO BE TREATED, INCLUDING AT LEAST ONE TANGENTIAL FILTRATION MEMBRANE. PURPOSE OF THE INVENTION IS TO PROVIDE A NEW TANGENTIAL MEMBRANE FILTRATION FACILITY WITH OZONE INJECTION, WHICH ALLOWS THE LIMITING OF THE SURFACE, INTERNAL AND CHEMICAL COLLATION OF THE MEMBRANE. ACCORDING TO THE INVENTION, THE FACILITY INCLUDES SOME MEANS (2) OF ADDITION OF AN OXIDIZING GAS TO THE LIQUID TO BE TREATED, IN THE LOOP MORE ABOVE THE MEMBRANE IN ORDER TO FORM SOME MICROPOMPAS OF SUCH GAS SUCH AS THEY CREATE A TURBAN IN THE LIQUID TO THE RIGHT OF THE MEMBRANE THAT, COUPLED TO THE OXIDATION PHENOMENON, LIMIT THE COLMATADO OF SUCH MEMBRANE (1) AND LEAD TO THE IMPROVEMENT OF THE FLOW RATE AND THE PHYSICOCHEMICAL QUALITIES OF THE FILTERING. IN CASE, IT INCLUDES SOME MEANS (10) OF INJECTION OF CHEMICAL REAGENTS AND / OR ADSORBENTS IN THE FILTRATION LOOP.
